Abstract
A display panel and a display device are provided in the present disclosure. The display panel includes a display region and a non-display region surrounding the display region. The display region includes a plurality of fingerprint recognition units. The non-display region includes a drive chip and Q first gate drive circuits, where the drive chip includes a first encoding circuit including M signal output terminals. The non-display region further includes a first decoding circuit and M first signal lines. The first decoding circuit includes M signal input terminals and N signal output terminals, where 1≤M<Q≤N, and M, Q, N are positive integers. A signal output terminal of the first encoding circuit is electrically connected to a corresponding signal input terminal of the first decoding circuit through one first signal line; and each first gate drive circuit is connected to one signal output terminal of the first decoding circuit correspondingly.
